BTFIXUP is basically a kernel boot time patching service, but
it only works if we can declare function prototypes in the
sparc specific header files.

Since do_gettimeofday() doesn't fall into that requirement, the code
in pci_time_init() is patching the first two instructions of
do_gettimeofday() such that is makes a call to pci_do_gettimeofday().
